Mini keyboard for the propeller
I am looking for a mini keyboard for the propeller.
Dimensions smaller than 10.5x 7.
Anybody using one this small ?

There is a really small keypad (not a keyboard) in this thread:

the chatpad has a programmable PIC inside it from what i hear
The place to find out is Wikipedia's article on 'Linux for XBox'. There is a similar one of PlayStation.

Very nice !, Did you get the keyboard to function with the propeller?
I like that keyboard, It looks to be the best candidate I have seen so far. I would remove the outer housing and just use the keyboard.

the only reason i still want to use the chatpad is because its backlit, its sexier, its easily available (i can pick one up at walmart cheap). yes i think its usb but once u flash the PIC with your own code its what ever u want it to be.
here's where someone hacked a chatpad to work with a PSP

It is a very nice piece of hardware and would really be nice with the Propeller, but I still believe that it is USB only. How does one identify the PIC chip and change over i/o?

The PICmicro is identified in the earlier links to photos - 16F883. Re-flashing shouldn't be that hard.
The 16F883 doesn't have USB on-chip so it seems unlikely the keypad uses USB. Not impossible but it would seem to be pointless extra cost and require a USB hub in the handset. More likely the handset ( if that uses USB ) can take button pushes and keypad data when connected and turn that into USB.
Re-coding would require decoding the circuit and choosing an I/O pin to transmit on. Presumably for the PSP interface much of that work has already been done.
Four wires is just as likely +V, 0V, TX and RX. If its protocol can be identified and is manageable there shouldn't be any need to re-program.

You just need a BT module to connect to it...
*Sigh* Yet another project I never seems to have the time to begin on...
(I have the EmbeddedBlue module somewhere among all the boxes in the room which will one day become my 'office' )
Maybe an idea for all the Hydra users out there?
Or in car computers... or home automation... or...

Don't visit my new website...
Maybe I should have used Ebay's Want it Now to ask just for keyboards. They were a big surplus item at one time and are probably still sitting around.
I haven't gotten around to working with these yet, but as I recall, the keyboard interface is 14 leads wide.
Ebay has one for sale in buy it now for $30 plus shipping. But the listing's photograph might be useful.

I have decided on a Mini-Keyboard I found on e-Bay.
Here's the link.

I feel that this may be the best fit for my project. It has already shipped, Well see ?
Thanks guy's for all the great info !

Fred,
Just opened up one of my dead TI-99A units.. What a keyboard! Not only small, and industrially well built!
Did you get around to interfacing one of these yet?
OT: Was thinking that perhaps the sound chip might also be interesting on the Prop.
(can't identify it on this board, must have a different part number than I'm expecting)
